What Causes Severe Headaches With Neck Pain And Vertigo?
It's Horner Syndrome
Detailed Answer:
Dear
I am sorry for the symptoms you are suffering.
It's seems your doctor has done a good examination, it's Horner Syndrome.
Not just for difference between eyes but even for the other symptoms you are suffering.
You need absolutely to contact your neurologist, and in the meantime schedule a brain MRI and MRA.
I think it is wise to present to an emergency room during one episode of headache because clinical examination at that time and brain CT or EEG can lead to the right diagnosis. Routine appointments with schedule may not be ideal for diagnosis.
Anyway I don't think you are suffering from an urgent neurology disease however timely examination and on spot findings and investigations makes easier to diagnose.
Hope my answer helps you

Anyway if symptoms persist you can try betahistine.
